I started writing the first edition back in 2011. Back then, OpenStack Diablo was THE production ready release. It had many promises and I was keen to learn more after dipping my toes into the OpenStack water with the Bexar release months before. Of course, I pronounced this wrong. So much for a country who frowns upon our additional characters in the English language.

This book was very popular and has taken me on a journey I wasn’t expecting. As time went on, Diablo wasn’t as hot property as it sounds and after being approached by none other than Cody Bunch who convinced me to write another, the 2nd Edition was needed. This was another 10 months getting a “few updates” in the book. This was published in June 2013 and was based on Grizzly.

Fast forward towards the end of 2014 and through a mental lapse, Cody yet again thought it might be a good idea to do another. Along the way of ideas, we picked up the esteemed Egle Sigler. Putting in a few more updates and with 50% more help, this would be a breeze to get the book updated for Juno. Or so we thought.

About 8 months later, we made it. We have updated sections that include how to install the very latest OpenStack Kilo using Ansible. Over 110 recipes has had an upgrade, rewrite or is a brand new addition to the book. We listened and we have a book that takes you through all the essential components and much more. We take you through step by step instructions on how you could run this in your datacentres.

We wouldn’t have made this possible without the immense valuable feedback from our tech reviewers. Thank you for keeping us on track and making this book even better than it was going to be:
